SD Card Reader Works only after reboot

My SD card reader (Realtek) won't work if my laptop is already running & I insert an SD card. However, if I put the card in and reboot the laptop it will allow me to access the card. I couldn't find it in the device selection, but I'm using a Dell Inspiron 5559 running Windows 10.

I have uninstalled and reinstalled the driver from Dell's website, removed and Dell driver and downloaded a driver directly from Realtek, but nothing I do makes the card reader work except rebooting the computer, which is becoming a real pain in the butt.

Any suggestions would be greatly appreciated. Thanks!
